Karousel bearing upgrade kit - LINN

That vital union between the platter, spindle, bearing and sub-chassis is now the strongest we’ve ever achieved. A new diamond-like carbon coating inside the bearing reduces friction between the tip of the spindle and the base of the bearing itself. This reduces the ‘noise floor’ of the turntable, so improves musical reproduction.
